2 Unit to ol pUnch & Die
Unittools 3/4" wide holders permits holes to be pierced up to 5/16" diameter on 3/4" centers. Six models are available.
The Single Spring – 6-1/4" shut height units are recommended where maximum shut height is not great enough to accommodate the features available in the double and triple spring – 7-1/2" shut unit heights. The Double Spring – 7-1/2" shut height unit is recommended for most applications for piercing up to a 5/16" diameter hole in 12 gauge material. The Triple Spring – 7-1/2" shut height unit offers still greater stripping forces and is recommended for the “tough” applications – where the units are stacked up against one another. This unit will pierce up to 5/16" diameter hole in 10 gauge material. The adjustable punch head offered on these double and triple spring units provides greater cost savings by increasing punch life. The punch assembly can be adjusted to “new length” after sharpening.
Several different dies are available. Selection of most suitable die for the application can have an economical advantage. Still greater savings can be realized by “shimming up” the die after excessive sharpening. This feature also permits a constant die height that eliminates material distortion resulting from punching with irregular die heights. The split bore feature provided in the pedestal at die section of the holder permits easy removal of die. This fea-ture allows the die bore to be self adjusting in event of excessive wear.
Small extrusions are readily punched on close hole centers. Ped-estal dies allow holes to be punched close to inside leg of angle or other obstructions.
Adjustable base units have 11/2" adjustment (3/4"each side of center-line) for punching stag-gered hole patterns.
